It would be 100% cool if it functioned w other assemblies besides their own

I'm pretty well sold on it! It's nice to see an affordable conversion. Especially one with last round BHO

i haven't watched the whole video yet; but for the price of this conversion, i could just get a 9mm lower and have another ar. idk thats just me

Mac: Please do a test on the Kaw Valley XL 9mm AR Linear Comp.
I know it reduces perceived noise, although of course not as much as a suppressor,
Would be interesting to see a review on it though. Without the availability of a suppressor it could offer some degree of hearing protection in something like a home defence situation.

what do you think about you Holosun HS510C?
There are up/right markings on the last Holoun productions

Mac put his ears on and I turned my volume up like I wasn’t going I be able to hear him. 😂😂😂

Mac, just how "non-marring" was that set screw?

Like the video but this kinda seems pointless to me. If you want a 9mm buy an mp5 or something. Somebody care to explain why this is popular and/or being used?

That thing suppressed is just stupid quiet

Cool And easy way on how to convert your AR-15 into a 9mm. Thanks for the knowledge Tim and I love your channel, keep up the great inventions from different gun companys.

Still Cheaper than buying a CZ or similar 9mm carbine…if you have an extra AR and Glock laying around. Glad I’ve got that extra AR, thanks nice video!

5000 round torture test please…

Why are they $200? That's so expensive! Even the colt mag conversion from precision firearms is $170. I don't understand why they are more than lowers themselves. I understand the math of producing a product like this. I just think it is overly expensive. I bought one bc I wanted one, I just don't get it.

Great video until the yankee marshal was mentioned. Screw that ahole

Pretty neat. But for the same money you can buy the FX9 complete rifle.

Pretty cool video, and yes, 9mm carbines are hard to beat in the fun department. As for self defense, a 9mm SBR with a silencer is hard to beat as (1) you're unlikely to be wearing hearing protection when you need it and (2) firing unsuppressed at night inside a house can put your eyes and ears out of commission really quick. You can assume the same thing for a 45ACP carbine, but they won't fit in and AR lower. A few years ago I bought a YHM Phantom 9mm upper, and then I later SBR'd it to 10.5", swapped… Read more »

They are demonetizing channels that are 2A friendly then playing anti gun adds before the videos…. sneaky sneaky

Obvious question for MAC… WHEN IS THIS GOING TO BE AVAILABLE IN 10MM??!!?? 🙂

Thanks for the video. How much money would it take for you to shave your beard off?

Edgar Coyle

Finally! One echo trigger in a lower and you can switch between 5.56 300BLK and 9mm. Thank you MAC, I will be purchasing one immediately

What actuates the bold hold open? Is it something in the lower, upper, conversion kit?

Marlon Wilks

For some odd reason I wanted you to shoot down a tree in this video lol

What was the total round count? All flawless, yes? (I'm WAY MORE INTERESTED in "testing" type videos for stuff like this than pistols buried in mud). You should blaze a case and film it from beginning to end, no cuts.

Justin Blais

You should look into a actually production HOLOSUN. I bought my fourth one on black friday. So far they all work great and at a pretty good price point. They all have markings on the ""turret""

MAC, will it accept the shorter Gen3 G19 mags?

That's pretty cool

Hi Tim interesting and fun video as you always makes ´em 🙂
I got a question regarding your collection of historic firearms and oddballs.

Do you have an old Remington rolling block in 12,7*44 in your collection ?
If you have would you mind making an video with it?
At least here in Sweden the amo is not easy getting by and I´ve had the pleasure of shooting one once 15 years ago and it was a pleasue. Mild recoil and fun to try 🙂

Mac thank you for great content

Won't that beat the hell put of a standard AR buffer? I had to put a heavy carbine Buffer in my 9mm conversion.

$325+ for a mag well and a 9mm bolt carrier group? And that doesn’t include the upper or barrel. Kind’a pricey.
I rather buy a dedicated 9mm complete lower.
This would be good for someone that is limited to buying only one AR, but lets be honest who owns just one AR right? 😅
Nice review.

The main benefit of a PCC is the ability to shoot in the local USPSA matches. There aren't that many two or three gun matches where I live, and one of the only places that runs them is 80 miles away. However there are three clubs not more than 45 minutes from my house that host monthly pistol matches, and you can shoot all of them with a16 in PCC.

Hey MAC, speaking of magloaders, I'm curious if you've tried the new ETS brand magloaders and wondered what you thought about them vs. the Uplula.

Jonathan Hassler

Tim would cmmg guard in 9mm would be a better but more expensive choice?

Alex S
Guest

What weight buffer and spring were you using? That seems to be the Achilles heal for the 9mm carbine to get them to function right?

Biggus Mickus
Guest

Would that kit fit on your M16 lower for full auto antics? Or is mentioning full auto illegal now?

Is it because 17 is a prime number?

I would like to see this conversion in the 10mm cartridge. Also prefer that they take Sig p320 magazines instead.

Cool product. I had ideas for something like this a while back. They should modify the mag release so that you could use it like a paddle mag release too.
